conclusions drawn about the suitability of such projects tocomplement traditional lecture-based instruction.II. PROJECT BACKGROUNDThe UTC, as depicted in Figure 1, is a solar energy conversion technology which relies upon adark colored perforated plate to absorb energy from the sun which is then transferred toincoming ventilation air. Doing so reduces the amount of fossil fuel consumption necessary toraise the ventilation air temperature to the building’s supply air requirement. A study of thesystem involves many competing and complementary forces which do not lend themselves to asimplified solution. The intent of the MSU project was to determine experimentally how thesesystems perform in a Minnesota climate. The results have shown that UTCs are

technique to fit a specific classroomenvironment.1. INTRODUCTIONFinding the time and opportunity to incorporate active and collaborative learning in your classescan be challenging. Team testing is a collaborative learning activity with low implementationcosts and multiple advantages for both students and faculty. Along with the obvious benefit ofdeveloping team problem solving and discussion skills, students receive fast feedback on theirperformance, the instructor spends less time reviewing the exam (in class and with individuals),and the classroom environment benefits from the added value placed on collaboration andreciprocal learning. This paper describes a number of variations on the team testing idea anddiscusses how factors in the course

Web-based courses would allow these students to spend less timeaway from their homes, saving them money while attracting more students.We decided to put our senior classes on the web to allow students to take these classes remotely.Because we did not have the faculty or budget to also offer these classes face-to-face, it wasinitially planned to make all senior classes web-based over a period of years. In 2003, theMinnesota State Colleges and University System (MNSCU) was instituted to assist statecampuses in developing on-line curricula and services2, and, in 2004, provided grants to theMET program to put classes on-line.1 We chose to implement an almost-entirely web-basedformat, with only one on-campus class meeting per semester to

Each team has two options for the completion of the project, one of which must becompleted. All graduate students must complete Option 2.Option 1: Record variable frequency logic data (50% duty cycle) for five seconds withsignal frequencies up to 3 kHz. Then, play the recorded data through the protoboardspeaker using appropriate interface circuitry.

delivery dates spread out over several weeks of the fall. Eachof these teams is responsible for receiving and managing the data that customers send to the labfor new model training, using the following process: 1. A student contacts the customer to establish delivery dates. Customers already have an expectation that new models and software will be delivered to them. The customer uses an automated tool to transmit data to the GasDay Lab. 2. A student generates a “data suspects report” that is reviewed with GasDay faculty, and used to work with the customer to correct errors. 3. Once data is cleaned a student will submit a job to GasDay’s compute cluster for model training. This processing typically requires one to three

For a majority ofengineering programs, the calculus math sequence is the key factor in the time to graduation dueto the prerequisites required for engineering and physics courses. For a student to complete theirengineering degree in four years, they need to start in calculus 1 in the fall of their first year andsuccessfully complete all of their math and other STEM courses on the first attempt and in aspecified order.This study analyzes the impact of condensed scheduling on graduation rate and time tograduation in Itasca C C e e engineering program.
